我尝试用SRT编译gst-plugins-bad，编译成功但找不到插件。我认为缺少依赖库srt和正确的参数（我使用了 --with-srt）。这些是我使用的命令：
git clone git://anongit.freedesktop.org/git/gstreamer/gst-plugins-bad
cd gst-plugins-bad
git checkout 1.14.2
export LDFLAGS='-L/opt/vc/lib' \
CFLAGS='-I/opt/vc/include -I/opt/vc/include/interface/vcos/pthreads -I/opt/vc/include/interface/vmcs_host/linux' \
CPPFLAGS='-I/opt/vc/include -I/opt/vc/include/interface/vcos/pthreads -I/opt/vc/include/interface/vmcs_host/linux'
./autogen.sh --disable-gtk-doc --disable-examples --disable-x11 --disable-glx --disable-glx --disable-opengl --with-srt
make CFLAGS+="-Wno-error -Wno-redundant-decls -I/opt/vc/include -I/opt/vc/include/interface/vcos/pthreads -I/opt/vc/include/interface/vmcs_host/linux" \
CPPFLAGS+="-Wno-error -Wno-redundant-decls -I/opt/vc/include -I/opt/vc/include/interface/vcos/pthreads -I/opt/vc/include/interface/vmcs_host/linux" \
CXXFLAGS+="-Wno-redundant-decls" LDFLAGS+="-L/opt/vc/lib"
用 SRT 编译的正确方法是什么？
